RESUMEN
INTRODUCTION: Previous studies have focused on outcomes pertaining to resident operative autonomy, but there has been little academic work examining the types of patients and cases where autonomy is afforded. We sought to describe the differences between surgical patient populations in teaching cases where residents are and are not afforded autonomy. METHODS: We examined all general and vascular operations at Veterans Affairs teaching hospitals from 2004 to 2019 using Veterans Affairs Surgical Quality Improvement Program. Level of resident supervision is prospectively recorded by the operating room nurse at the time of surgery: attending primary (AP): the attending performs the case with or without a resident; attending resident (AR): the resident performs the case with the attending scrubbed; resident primary (RP): resident operating with supervising attending not scrubbed. Resident (R) cases refer to AR + RP. Patient demographics, comorbidities, level of supervision, and top cases within each group were evaluated. RESULTS: A total of 618,578 cases were analyzed; 154,217 (24.9%) were AP, 425,933 (68.9%) AR, and 38,428 (6.2%) RP. Using work relative value unit as a surrogate for complexity, RP was the least complex compared to AP and AR (10.4/14.4/14.8, P < 0.001). RP also had a lower proportion of American Society of Anesthesiologists 3 and 4 + 5 patients (P < 0.001), were younger (P < 0.001), and generally had lower comorbidities. The most common RP cases made up a higher proportion of all RP cases than they did for AP/AR and demonstrated several core competencies (hernia, cholecystectomy, appendectomy, amputation). R cases, however, were generally sicker than AP cases. CONCLUSIONS: In the small proportion of cases where residents were afforded autonomy, we found they were more focused on the core general surgery cases on lower risk patients. This selection bias likely demonstrates appropriate attending judgment in affording autonomy. However, this cohort consisted of many "sicker" patients and those factors alone should not disqualify resident involvement.

INTRODUCTION: Surgical resident operative autonomy has decreased markedly over time, reducing resident readiness for independent practice. We sought to examine operative resident autonomy for emergency acute care surgery (ACS) compared to elective cases and associated patient outcomes at veterans affairs hospitals. METHODS: The Veterans Affairs Surgical Quality Improvement Program database was queried for ACS cases (emergency general, vascular, and thoracic) at veterans affairs hospitals from 2004 to 2019. Cases are coded prospectively for the level of supervision: attending primary surgeon (AP); attending scrubbed with resident surgeon (AR); resident primary (RP), attending not scrubbed. Baseline demographics, operative variables, and outcomes were compared. RESULTS: A total of 61,275 ACS cases and 605,146 elective cases were performed during the study period. The ACS had a higher proportion of RP cases (7.2% versus 5.7%, P < 0.001). The proportion of ACS RP cases decreased from 9.9% to 4.1% (58.6%); elective RP cases decreased from 8.9% to 2.9% (67.4%). The most common ACS RP surgeries were appendectomy, amputations, and cholecystectomy. RP cases had lower American Society of Anesthesia class and lower median work relative value units than AP and AR. There was no difference between mortality rates of RP compared to AP (adjusted odds ratio [OR] 0.94 [0.80-1.09] or AR 0.94 [0.81-1.08]). While there was no difference in complications between the RP and AP (OR 1.01 [0.92-1.12]), there were significantly more complications in AR compared to RP (OR 1.20 [1.10-1.31]). CONCLUSIONS: More autonomy is granted for ACS cases compared to elective cases. While both decreased over time, the decrease is less for ACS cases. Resident autonomy does not negatively impact outcomes, even in emergent cases.

INTRODUCTION: We have previously shown that resident autonomy has decreased over time overall for all surgery residents. The purpose of this study is to examine changes in operative autonomy in general surgery residency within each postgraduate year (PGY) level. MATERIALS AND METHODS: This is a retrospective analysis of the Veterans Association Surgical Quality Improvement Program database from July 1, 2004 to September 30, 2019. All general surgery, vascular surgery, and thoracic surgery procedures were analyzed and categorized by level of resident supervision as attending primary, attending operating with resident, or resident primary without attending scrubbed. Procedure work portion of relative value unit was used to capture procedure complexity. Changes in resident autonomy over time, procedure complexity, and outcomes were compared among PGY levels 1 to 5. RESULTS: A total of 385,482 cases were analyzed. At each PGY level from 2014 to 2018, the relative decrease in resident primary cases ranged from -37.3% (PGY 4) to -75.5% (PGY 3). Mean work portion of relative value unit saw steady increase with PGY level (8.4 ± 3.5 in PGY 1 to 10.8 ± 5.7 in PGY 5, P < 0.001) and did not show a trend over time. CONCLUSIONS: Surgical resident operative autonomy has markedly decreased over time across all PGY levels. This effect is most profound at the PGY 3 level, while more senior residents are affected to a lesser degree. Case complexity show PGY level-appropriate increase in resident autonomous cases. Decrease in resident autonomy over time is not associated with changes in case complexity.
RESUMEN
INTRODUCTION: With improved technology and technique, laparoscopic inguinal hernia repair (LIHR) has become a valid option for repairing both initial and recurrent inguinal hernia. Surgical residents must learn both techniques to prepare for future practice. We examined resident operative autonomy between LIHR and open inguinal hernia repair (OIHR) across the Veterans Affairs (VA) system. METHODS: Utilizing the VA Surgical Quality Improvement Program database, we examined inguinal hernia repairs based on the principal procedure code at all teaching VA hospitals from July 2004 to September 2019. All VA cases are coded for level of supervision at the time of surgery: attending primary surgeon (AP); attending scrubbed but resident is a primary surgeon (AR), and resident primary with attending supervising but not scrubbed (RP). Primary outcomes were the proportion of LIHR versus OIHR and resident autonomy over time. RESULTS: A total of 127,497 hernia repair cases were examined (106,892 OIHR and 20,605 LIHR). There was a higher proportion of RP (8.7% vs 2.2%) and lower proportion of AP (23.9% vs 28.4%) within OIHR compared to LIHR (p < 0.001). The overall proportion of LIHR repairs increased from 9 to 28% (p < 0.001). RP cases decreased for LIHR from 9 to 1% and for OIHR from 17 to 4%, while AP cases increased for LIHR from 16 to 42% and for OIHR from 18 to 30% (all p < 0.001). For RP cases, mortality (0 vs 0.2%, p > 0.99) and complication rates (1.1% vs. 1.7%, p = 0.35) were no different. CONCLUSIONS: LIHR at VA hospitals has tripled over the past 15 years, now compromising nearly one-third of all inguinal hernia repairs; the majority are initial hernias. Despite this increase, resident autonomy in LIHR cases declined alarmingly. The results demonstrate an urgent need to integrate enhanced minimally invasive training into a general surgery curriculum to prepare residents for future independent practice.

BACKGROUND AND AIMS: Traditional management for infected necrotizing pancreatitis (INP) often utilizes open necrosectomy, which carries high morbidity and complication rates. Thus, minimally invasive strategies have gained favor, specifically step-up approaches utilizing endoscopic or minimally-invasive surgery (MIS); however, the ideal management modality for INP has not been identified. METHODS: A decision tree model was designed to analyze costs and survival associated with open necrosectomy, endoscopic step-up, and MIS step-up protocols for management of INP after 4 weeks of necrosis development with adequate retroperitoneal access. Costs were based on a third-party payer perspective using Medicare reimbursement rates. The model's effectiveness was represented by quality-adjusted life-years (QALYs). Sensitivity analyses were performed to validate results. RESULTS: Endoscopic step-up was the dominant economic strategy with 7.92 QALYs for $90,864.09. Surgical step-up resulted in a decrease of 0.09 QALYs and a cost increase of $10,067.89 while open necrosectomy resulted in a decrease of 0.4 QALYs and an increased cost of $18,407.52 over endoscopic step-up. In 100,000 random-sampling simulations, 65.5% of simulations favored endoscopic step-up. MIS step-up was favored when MIS acute mortality rates fell and when MIS drainage success rates rose. CONCLUSIONS: In our simulated patients with INP, the most cost-effective management strategy is endoscopic step-up. Cost-effectiveness varies with changes in acute mortality and drainage success, which will depend on local expertise.

BACKGROUND: Sentinel lymph node biopsy (SLNB) has shown promise in identifying subclinical nodal metastasis in patients with high-risk cutaneous squamous cell carcinoma. However, low metastasis rates may indicate that performing such a procedure in all patients may be unnecessary and costly. MATERIALS AND METHODS: A decision model was developed to analyze costs and survival in patients with head and neck cutaneous squamous cell carcinoma based on their tumor and nodal metastasis staging and whether or not they received an SLNB. Incremental cost-effectiveness ratios were calculated based on the change in quality-adjusted life years (QALYs) and costs (US$) between the different options, with a threshold of $100,000 to determine the most cost-effective strategy. One-way, two-way, and probabilistic sensitivity analyses were performed to validate the results. RESULTS: Not performing an SLNB results in 12.26 QALYs and a cost of $3712.98. Performing an SLNB resulted in a 0.59 decrease in QALYs and an increase in cost of $1379.58 for an incremental cost-effectiveness ratio of -2338.27. This trend remained the same across all tumor stages and remained consistent within most sensitivity analyses. CONCLUSIONS: In patients with head and neck cutaneous squamous cell carcinoma, the most cost-effective strategy is to not perform SLNBs, regardless of the patient's stage. Low rates of nodal metastasis in addition to low disease-specific death rates were the significant factors in this outcome. Increasing the sensitivity of SLNB would not impact this recommendation unless the rate of nodal metastasis was significantly higher.

The safety and liver utilization with prerecovery liver biopsy (PLB) in extended criteria liver donors are unclear. We conducted a retrospective cohort study in 1323 brain death donors (PLB = 496) from 3 organ procurement organizations (OPOs). Outcomes were complications, preempted liver recovery (PLR), and liver transplantation (LT). Additional analyses included liver-only and propensity score-matched multiorgan donor subgroups. PLB donors were older (57 versus 53 years; P < 0.001). Hepatitis C antibody positivity (14.3% versus 9.6%, P = 0.01) and liver-only donors (42.6% versus 17.5%; P < 0.001) were more prevalent. The PLB cohort had fewer complications (31.9% versus 42.3%; P < 0.001). In the PLB cohort, PLR was significantly higher (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.42-4.92) and LT lower (OR, 0.69; 95% CI, 0.52-0.91). In liver-only and propensity score-matched multiorgan donor subgroups, PLR was significantly higher (OR, 1.76; 95% CI, 1.06-2.94 and OR, 2.29; 95% CI, 1.37-3.82, respectively) without a decrease in LT (OR, 0.71; 95% CI, 0.43-1.18 and OR, 0.91; 95% CI, 0.63-1.33, respectively) in PLB subgroups. In conclusion, in extended criteria liver donors, PLB is safe and decreases futile liver recovery without decreasing LT. Increased use of PLB, especially in liver-only donors, is likely to save costs to OPOs and transplant centers and improve efficiencies in organ allocation.

BACKGROUND: Cytoreduction surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) improve survival and decrease recurrence of peritoneal metastasis in a select population of patients. Abdominal wall resection is often needed to achieve complete CRS and the extent of abdominal wall resection may necessitate abdominal wall reconstruction (AWR). We sought to investigate if postoperative morbidity and mortality was increased in patients who underwent AWR with CRS-HIPEC (AWR group) compared to CRS-HIPEC without AWR (non-AWR group) and to identify if patient, tumor, and operative risk factors were associated with poor outcomes following AWR. We postulate that AWR is a safe and viable treatment option in appropriately selected patients with peritoneal disease. METHODS: A retrospective chart review was conducted from 2012 to 2015. Demographics, comorbidities, intraoperative variables, and postoperative outcomes were analyzed and compared between the non-AWR group and the AWR group. RESULTS: A total of 30 patients underwent CRS-HIPEC at our institution; 19 recruited in non-AWR group and 11 in the AWR arm. Median follow-up was 19.1 mo for the non-AWR group and 15.6 mo for AWR. Overall survival and complications were not significantly different between groups. Six patients in the non-AWR group and three patients in AWR group died during the follow-up period (32% versus 27%, P = 0.75). Grade III/IV Clavien-Dindo complications were similar in AWR compared to non-AWR group (64% versus 50%, P = 0.46) however estimated blood loss (1000 mL versus 450 mL, P = 0.01) and operative time (663 min versus 510 min, P = 0.02) were significantly increased in the AWR group. CONCLUSIONS: The results of this study demonstrate that AWR is a safe and viable option and can improve wound closure and strength in select patient populations undergoing CRS-HIPEC. AWR is not associated with an increase in mortality or complication rate. Future studies will need larger sample sizes and randomization to identify patient and operative factors that increase morbidity with AWR and identify the ideal timing of AWR.

BACKGROUND: Medical malpractice is a growing concern for physicians in all fields. Surgical fields have some of the highest malpractice premiums and litigation rates. Pancreaticoduodenectomy (PD) has become a popular procedure; however, it is still associated with significant morbidity and mortality. This study is the first to analyze factors involved in litigation regarding PD cases. METHODS: The Westlaw database was searched for jury verdicts and settlements using the terms "medical malpractice" and "pancreaticoduodenectomy". Twenty-nine cases from 1991 to 2012 were initially collected. Seven entries not involving PD and three duplicate cases were excluded. Nineteen cases were included for analysis. RESULTS: Of the 19 cases included in the analysis, three (15.8%) reached a settlement, three (15.8%) were ruled in favor of the plaintiff, and 13 (68.4%) were ruled in favor of the physician. The average settlement award was $398,333 (range, $195,000-500,000), and the average plaintiff award was $4,288,869 (range, $1,066,608-10,300,000). The most common factors raised in litigation included PD being allegedly unnecessary (47.4%), followed by postoperative negligence and misdiagnosis (36.8% each). CONCLUSIONS: The most common factors present in litigation included the allegation that PD was unnecessarily performed. The cases that are awarded large monetary sums are those that involve continued medical care. Ways to improve patient safety and limit litigation include increasing transparency and communication with a thorough discussion between surgeon and patient of the most common topics of litigation discussed.

BACKGROUND: Biliary stricture without mass presents diagnostic and therapeutic challenges because the poor sensitivity of the available tests and significant mortality and cost with operation. METHODS: A decision model was developed to analyze costs and survival for 1) investigation first with endoscopic ultrasound (EUS) and fine needle aspiration, 2) investigation first with endoscopic retrograde cholangiopancreatography (ERCP) and brushing, or 3) surgery on every patient. The average age of someone with a biliary stricture was found to be 62-y-old and the rate of cancer was 55%. Incremental cost-effectiveness ratios (ICER) were calculated based on the change in quality adjusted life years (QALYs) and costs (US$) between the different options, with a threshold of $150,000 to determine the most cost-effective strategy. One-way, two-way, and probabilistic-sensitivity analysis were performed to validate the model. RESULTS: ERCP results in 9.05 QALYs and a cost of $34,685.11 for a cost-effectiveness ratio of $3832.33. EUS results in an incremental increase in 0.13 QALYs and $2773.69 for an ICER of $20,840.28 per QALY gained. Surgery resulted in a decrease of 1.37 QALYs and increased cost of $14,323.94 (ICER-$10,490.53). These trends remained within most sensitivity analyses; however, ERCP and EUS were dependent on the test sensitivity. CONCLUSIONS: In patients with a biliary stricture with no mass, the most cost-effective strategy is to investigate the patient before operation. The choice between EUS and ERCP should be institutionally dependent, with EUS being more cost-effective in our base case analysis.

Pancreas transplantation venous effluent can be drained via the portal vein or the systemic circulation; however, no recommendation exists for the ideal technique. A systematic review of the literature from 1989 through 2014 using PubMed, CINHAL, and Cochrane Library for portal versus systemic venous drainage was undertaken. Only studies on humans and published in English were considered. Measures of glycemic control and total cholesterol were synthesized for meta-analysis utilizing random-effects models. Of 166 articles retrieved, 15 articles were included for meta-analysis. Patient and graft survival were comparable in a large database study as well as in the only randomized control study. No differences in complications were seen when exocrine drainage was enteric for the systemic venous group. Fasting insulin (-34.13 pmol/mL, p < 0.001) was significantly lower within the portal drained group; however, fasting blood glucose levels (-3.4 mg/dL, p = 0.32) and hemoglobin A1C levels (mean difference 0.124%, p = 0.25) were comparable. Total cholesterol levels (-3.62 mg/dL, p = 0.447), as well as other measures of lipids, showed no difference. Based on this systematic review and meta-analysis, there is no evidence of differences in outcomes or metabolic control in patients undergoing pancreatic transplant with portal venous drainage compared to the systemic venous drainage.

BACKGROUND: Biliary strictures present a diagnostic challenge to differentiate benign disease from hepatopancreaticobiliary (HPB) malignancies. Endoscopic retrograde cholangiopancreatography cytology is commonly performed in these patients; however, its sensitivity for diagnosis of HPB malignancy is poor (41.6%). Many adjunctive tests have been investigated to improve the sensitivity of HPB biopsies. To determine the best tests available, however, we reviewed the literature and performed a comparative analysis of all recently investigated tests and their sensitivities. METHODS: A PubMed search identified articles published between 2003 and 2014, describing alternate methods for diagnosing HPB malignancies, reported sensitivity, final pathology, and had data available online. Meta-analysis was conducted for tests with multiple articles. Tests with the highest sensitivity and specificities were reported. RESULTS: A total of 77 studies were identified. Meta-analysis was performed on the sensitivity of EUS-FNA (74.2%), fluorescence in situ hybridization (54.2%), immunostain of insulin-like growth factor 2 mRNA-binding Protein 3 (IMP3; 80.4%), IMP3 + cytology (86.4%), K homology domain containing protein overexpressed in cancer (KOC; 85.9%), S100P (77.8%), serum CA19-9 (69.3%), and K-ras mutations (47.0%) to detect malignancy. Ultimately, 12 tests were identified with superior sensitivity (85.3%-100%) and specificities (81.6%-100%) including stricture scrapping, brush sectioning, IMP3 stain + cytology, IMP3+S100A4, bile carcinoembryonic cell adhesion molecule 6 protein (±CA19-9), bile micro RNA (miRNA)-135b, serum miRNA-RNU2-1f, serum miRNA-21 (+CA19-9), peripheral blood mononuclear cells miRNA-27a-3p (+CA19-9), serum miRNA-16 + miRNA-196a (+CA19-9), peripheral blood mononuclear cells mRNAs h-TERT + CK20 + CEA + C-MET. CONCLUSIONS: We recommend immunostaining with a panel of IMP3+KOC + S100A4 + cytology to achieve maximum sensitivity and specificity from HPB biopsies. One biliary protein (carcinoembryonic cell adhesion molecule 6) and several RNAs (bile and blood) offer exceptional sensitivity and specificity and should be tested prospectively in larger populations. Overall, this review identifies several tests to improve the sensitivity of diagnostic algorithms to identify HPB malignancies.

BACKGROUND: During the COVID-19 pandemic, elective cases across the nation were suspended, leading to major decreases in operative volume for surgical trainees. Surgical resident operative autonomy has been declining over time, so we sought to explore the effect COVID-19 had on resident autonomy within VA teaching hospitals. METHODS: A retrospective analysis of surgical cases across specialties was performed using the VA Surgical Quality Improvement Program database from September 2019 to September 2021 at VA teaching hospitals. Supervision codes are recorded prospectively: attending surgeon performs the operation (AP), resident completes majority of the case with the attending scrubbed (AR), and resident is primary surgeon without attending scrubbed (RP). RESULTS: 20,457 cases pre-COVID decreased to 11,035 during peak-COVID (P < .001). Overall, RP cases increased from 6.5% to 7.6% during the peak (P < .001) and trended back downwards during the recovery periods. AP decreased initially (29.9%-27.7%, P < .001), but regressed back to pre-pandemic numbers. In general surgery RP cases, urgent cases such as laparoscopic cholecystectomies increased from 18.8% to 27.5%, while elective repairs decreased during the peak. Similar changes were noted across specialties. DISCUSSION: Operative cases dropped by half from pre- to peak- COVID and remained 20% below pre-pandemic volume the following year. Interestingly, RP rates increased for several specialties during the peak of the pandemic, which may have resulted from a relative higher ratio of resident personnel:case volume and shift in case distribution from elective to urgent. The increase in RP rate has begun to regress to pre-COVID levels which need to be readdressed.

Across the nation, patients with locally advanced gastric cancer (LAGC) are managed with modalities including upfront surgery (US) and perioperative chemotherapy (PCT). Preoperative therapies have demonstrated survival benefits over US and thus long-term outcomes are expected to vary between the options. However, as these 2 modalities continue to be regularly employed, we sought to perform a decision analysis comparing the costs and quality-of-life associated with the treatment of patients with LAGC to identify the most cost-effective option. We designed a decision tree model to investigate the survival and costs associated with the most commonly utilized management modalities for LAGC in the United States: US and PCT. The tree described costs and treatment strategies over a 6-month time horizon. Costs were derived from 2022 Medicare reimbursement rates using the third-party payer perspective for physicians and hospitals. Effectiveness was represented using quality-adjusted life-years (QALYs). One-way, two-way, and probabilistic sensitivity analyses were utilized to test the robustness of our findings. PCT was the most cost-effective treatment modality for patients with LAGC over US with a cost of $40,792.16 yielding 3.11 QALYs. US has a cost of $55,575.57 while yielding 3.15 QALYs; the incremental cost-effectiveness ratio (ICER) was $369,585.25. One-way and two-way sensitivity analyses favored PCT in all variations of variables across their standard deviations. Across 100,000 Monte Carlo simulations, 100% of trials favored PCT. In our model simulating patients with LAGC, the most cost-effective treatment strategy was PCT. While US demonstrated improved QALYs over PCT, the associated cost was too great to justify its use.

OBJECTIVE: The volume of cases that residents perform independently have decreased leaving graduating chief residents less prepared for independent practice. Outcomes are not worse when residents are given autonomy with appropriate supervision, however it is unknown if outcomes are worsening with decreasing operative autonomy experience. We hypothesize that resident autonomous cases parallel the improving outcomes in surgical care over time, however, are less complex and on lower acuity patients. DESIGN: Retrospective study utilizing the Veterans Affairs Surgical Quality Improvement Program (VASQIP) database. SETTING: Operative cases performed on teaching services within the VASQIP database from July 1, 2004 to September 30, 2019, were included. PARTICIPANTS: All adult patients who underwent a surgical procedure from July 1, 2004, to September 30, 2019, at a VA hospital on a service that included residents were initially included. After inclusions and exclusions, there were 1,346,461 cases. Cases were divided into 3 sequential 5 year eras (ERA 1: 2004-2008 nâ¯=â¯415,614, ERA 2: 2009-2013 nâ¯=â¯478,528, and ERA 3: 2014-2019 nâ¯=â¯452,319). The main exposure of interest was level of resident supervision, coded at the time of procedure as: attending primary surgeon (AP); attending and resident (AR), or resident primary with the attending supervising but not scrubbed (RP). We compared 30 day all-cause mortality, composite morbidity, work relative value unit (wRVU), hospital length of stay, and operative time between each ERA for RP cases, as well as within each ERA for RP cases compared to AR and AP cases. RESULTS: There was a progressive decline in the rate of RP cases in each successive ERA (ERA 1: 58,249 (14.0%) vs ERA 2: 47,891 (10.0%) vs ERA 3: 35,352 (7.8%), p < 0.001). For RP cases, patients were progressively getting older (60 yrs [53-71] vs 63 yrs [54-69] vs 66 yrs [57-72], p < 0.001) and sicker (ASA 3 58.7% vs 62.5% vs 66.2% and ASA 4/5 8.4% vs 9.6% vs10.0%, p < 0.001). Odds of mortality decreased in each ERA compared to the previous (aOR 0.71 [0.62-0.80] ERA 2 vs ERA 1 and 0.82 [0.70-0.97] ERA 3 vs ERA 2) as did morbidity (0.77 [0.73-0.82] ERA 2 vs ERA 1 and 0.72 [0.68-0.77] ERA 3 vs ERA 2). Operative and length of stay also decreased while wRVU stayed unchanged. When comparing RP cases to AP and AR within each ERA, RP cases tended to be on younger and healthier patients with a lower wRVU, particularly compared to AR cases. Mortality and morbidity were no different or better in RP compared to AR and AP. CONCLUSIONS: Despite resident autonomy decreasing, outcomes in cases where they are afforded autonomy are improving over time. This despite RP cases being on sicker and older patients and performing roughly the same complexity of cases. They also continue to perform no worse than cases with higher levels of supervision. Efforts to increase surgical resident operative autonomy are still needed to improve readiness for independent practice.

BACKGROUND: Examining surgical resident operative autonomy within the Veterans Affairs (VA) System, we previously showed residents were afforded autonomy more frequently on Black patients. We hypothesized that, compared to males, female surgical patients receive less attending involvement and more resident autonomy during surgery. METHODS: Retrospective review of all general/vascular surgeries performed at teaching VA hospitals from 2004 to 2019. Operative procedures are coded at the time of surgery as attending primary surgeon (AP), attending with resident (AR), or resident primary surgeon--attending not scrubbed (RP). The primary outcome was the difference in supervision rates between patient sexes. RESULTS: 618,578 operations were examined-24.9% AP, 68.9% AR, and 6.2% RP. Overall, 5.9% of cases were performed on women. The rate of RP cases was higher in males compared to females (6.3% vs 5.3%, p < 0.001). CONCLUSION: Female veterans are less likely to have residents operate on them autonomously. Reasons for this require further characterization.

Abdominopelvic varicosities are a rare occurrence after traumatic venous injuries. Several disorders exist that present with abdominopelvic varicosities such as May-Thurner syndrome, pelvic congestion syndrome, and nutcracker syndrome; however, it has rarely been described after trauma.1 We present a case in 70-year-old male, who in 1974 sustained a penetrating injury from fragments secondary to mortar explosion, requiring exploratory laparotomy. He presented to the hospital with abdominopelvic varicosities that began 20 years after the incident and was asymptomatic at initial presentation. While there is a known case report of congenital absence of a common iliac vein in a young, healthy, athletic man who developed abdominopelvic varicosities, this is the first case report, to our knowledge, of evolution of a traumatic injury of this nature over a lifetime. Pathophysiology, diagnostics, risks of ligation, and management of chronic abdominopelvic varicosities in this patient are discussed.

BACKGROUND: Surgical resident operative autonomy is critical for trainee maturation to independence. Acute care surgery (ACS) cases commonly occur off-hours and tension between operating room availability and on-call staff can affect resident operative autonomy. We examined operative resident autonomy for general, vascular, and thoracic (GVT) surgery during nights and weekends. We hypothesized that residents would be afforded less operative autonomy during off - hours than weekdays. METHODS: This retrospective cohort study uses the Veterans Affairs Surgical Quality Improvement Program database, we examined all GVT cases at Veterans Affairs teaching hospitals from 2004 to 2019. All cases are coded for the level of supervision at the time of surgery: AP, attending primary surgeon; AR, attending and resident operating together; and RP, resident primary (attending supervising but not scrubbed). Cases starting between 6 pm to 7 am Monday through Friday were considered nights, cases on Saturday/Sunday were considered weekends, and collectively considered "off-hours." Resident primary case rates were compared by start time and type. RESULTS: Over the 15-year study period, there were 666,421 GVT cases performed with 38,097 cases (6%) performed off-hours. During off-hours, 31,396 (83%) were ACS compared with 5% of daytime cases. Overall, off-hours cases have higher RP rate than daytime cases (6.8% vs. 5.8%, p < 0.001). Daytime ACS cases have higher rates of RP than nights/weekends (7.6% vs. 6.8%, p < 0.001). Conversely, daytime elective cases have lower RP than nights (5.7% vs. 7.9%, p < 0.001). During off-hours, there are more RP cases on nights compared with weekends (7.1% vs. 6.5%, p = 0.02). CONCLUSION: Overall, residents were afforded more operative autonomy during off-hours, with nights having greater RP than weekends. In contrast, ACS cases have more autonomy during weekdays. These data have potentially significant implications for ACS service staffing, night float rotations, and overall resident operative experience on ACS services. LEVEL OF EVIDENCE/STUDY TYPE: Prognostic and Epidemiological; Level III.

INTRODUCTION: Chronic opioid use is prevalent among patients undergoing emergent surgery. We sought to understand it on the outcomes of the most common emergency surgery procedures, Appendectomy and Cholecystectomy. METHODS: We used the National Inpatient Sample to identify chronic opioid use in emergency appendectomies (n = 953) and cholecystectomies (n = 2826) from 2005 to 2014. Primary outcome was length of stay (LOS), and secondary outcomes included total charges and mortality. LOS was analyzed with multivariate Poisson regression, total charges with multivariate linear regression. RESULTS: For Appendectomy, the opioid abuse group was younger, had similar gender and racial demographics, had more Medicaid and private insurance and less self-pay, and had no clinically significant differences in comorbidities. Those with chronic opioid use had a 24% increased LOS (20-29%, p < .001) and $5532(±$881, p < .001) higher hospital charges. Mortality was very rare and not different (0.2% vs 0.6%, aOR 0.54 [0.11-2.58], p = .44). For Cholecystectomy, the opioid abuse group was similar in age and gender, had slightly more white individuals, had a slightly different payor mix including higher rate of private insurance, and had no clinically significant differences in comorbidities. Patients with preoperative chronic opioid abuse showed a 14% increased LOS (12-16%, p < .001) and $5352 (± $1065, p < .001) higher hospital charges, but no significant increase in mortality (0.7% vs 0.6%, aOR 1.58 [0.77-3.25], p = .22). CONCLUSION: Patients with chronic opioid abuse did not have increased mortality following EGS but had increased resource utilization and LOS. These findings may help explore the impact of opioid abuse on hospital and societal cost.

IMPORTANCE: Resident operative autonomy has been steadily decreasing. Whether this reduction in autonomy has been associated with changes in patient outcomes is unclear. OBJECTIVE: To assess whether surgical procedures performed by residents without an attending surgeon scrubbed are associated with differences in patient outcomes compared with procedures performed by attending surgeons alone or by residents with the assistance of attending surgeons. DESIGN, SETTING, AND PARTICIPANTS: This retrospective propensity score-matched cohort study analyzed 30-day outcomes among patients who received operations at US Veterans Affairs (VA) medical centers and were recorded within the VA Surgical Quality Improvement Program (VASQIP) database from July 1, 2004, to September 30, 2019. Among 1â¯797â¯056 operations recorded in the VASQIP during that period, 1â¯319â¯020 were eligible for inclusion. Operations performed by a surgical resident without an attending surgeon scrubbed (resident primary) were propensity score matched on a 1:1 ratio (based on year of procedure and patient age, race, sex, American Society of Anesthesiologists physical status classification, functional status, emergency status, inpatient status, presence of multiple comorbidities, and Current Procedural Terminology code) to operations performed by an attending surgeon only (surgeon primary) and operations performed by a resident with assistance from an attending surgeon (resident plus surgeon). EXPOSURES: Level of resident involvement. MAIN OUTCOMES AND MEASURES: Thirty-day adjusted all-cause mortality. RESULTS: Among 1â¯319â¯020 surgical procedures included, 138â¯750 were performed by residents only, 308â¯724 were performed by surgeons only, and 871â¯546 were performed by residents and surgeons. For the 1â¯319â¯020 total cases, patients' mean (SD) age was 61.6 (12.9) years; 1â¯223â¯051 patients (92.7%) were male; and 212â¯315 (16.1%) were Black or African American, 63â¯817 (4.9%) were Hispanic, 830â¯704 (63.0%) were White, and 212â¯814 (16.1%) were of other or unknown race and ethnicity. Propensity score matching produced 101â¯130 pairs of resident-primary and surgeon-primary procedures and 137â¯749 pairs of resident-primary and resident plus surgeon procedures. Patient all-cause mortality and morbidity were no different among those who received surgeon-primary procedures (mortality: odds ratio [OR], 1.03 [95% CI, 0.95-1.12]; morbidity: OR, 1.01 [95% CI, 0.97-1.05]) vs resident plus surgeon procedures (mortality: OR, 1.03 [95% CI, 0.97-1.11]; all-cause morbidity: OR, 0.97 [95% CI, 0.95-1.00]). Resident-primary procedures had longer operative times than surgeon-primary procedures (median, 80 minutes [IQR, 50-123 minutes] vs 70 minutes [IQR, 41-114 minutes], respectively; P < .001) but shorter operative times than resident plus surgeon procedures (median, 71 minutes [IQR, 43-113 minutes] vs 73 minutes [IQR, 45-115 minutes]; P < .001). Hospital length of stay was unchanged among resident-primary vs surgeon-primary procedures (median, 4 days [IQR, 2-10 days] vs 4 days [IQR, 2-9 days]; P = .08) and statistically significantly shorter than resident plus surgeon procedures (median, 4 days [IQR, 1-9 days] vs 4 days [IQR, 2-10 days]; P < .001). CONCLUSIONS AND RELEVANCE: In this cohort study, surgical procedures performed by residents alone were not associated with any changes in all-cause mortality or composite morbidity compared with those performed by attending surgeons alone or by residents with the assistance of attending surgeons. Given these findings and the importance of operative autonomy to prepare surgical residents for independent practice, efforts to increase autonomy are both safe and needed.
